What are those little circles after each week on the calendar modification page?
The circles are used for selecting and clearing the entire week. If your browser does not support javascript or you have javascript disabled, they will not work. Clicking the top circle will check every day in the week, while clicking the bottom circle will clear the checks from every day in the week. We are considering circles for selecting and clearing full months, but due to space limitations on the display, we will wait for more feedback on this feature.
